90° horizontal X +20 to -30° vertical (50° total, adjustable mount provides for vertical plane adjustments.
The horizontal plane can be adjusted by altering mounting position on the low frequency enclosure before
tightening bolts.

[Bi-amp mode] 105 dB SPL, 1 watt, 1 meter
[Tri-amp mode] 250 Hertz or higher, 24dB/octave and 1.7k Hertz, 24dB/octave
[Bi-amp mode] 250 Hertz or higher, 24dB/octave
1.7k Hertz, 18 dB/octave electrical slope, HF driver power limiting circuit (never disrupts continuity). Swit-
chable operation between Bi-Amp and Tri-amp operation. Tri-amp setting removes crossover circuit from
signal, leaving power limiter and DC blocking capacitors.
Barrier strip screw terminals accept up to #10 AWG (6mm
and two MF input (for Tri-amp mode operation).
MF: 10" high efficiency midrange, phase-ring loaded.
HF: 1.5" (38mm) exit, 3" (76mm) voice coil, titanium diaphragm compression driver.
Attaches to top of the low frequency cabinet using three M8, 20mm long bolts.
